ESP8266 Download Tool Parameter Discrepancy

[jimyates]

I am trying to program the WROOM-02, but there is a discrepancy in between the configuration shown on boot of the wroom-02 and that shown by the ESP8266 download tool. When the wroom boots, listening to the UART at 74880 baud, I receive the following message:

ets Jan 8 2013,rst cause:1, boot mode:(3,6)

but when I run the ESP8266 download tool, the DETECTED INFO block shows:

flash vendor:
A1h : FM
flash devID:
4016h
QUAD;32Mbit
crystal:
26 Mhz


So which should I believe when programming the device?

Should I use DIO or QIO?
Should I use 8Mbit, or 32Mbit?
What addresses should I use for default.bin, blank.bin, user1 bin, and user2 bin?

Hi,

8Mbit(512KB+512KB) is the flash map you selected on the ESP Flash Download Tool when downloading.

QUAD;32Mbit is the actual size of your flash.

So it means that you are using a 32Mbit flash as a 8Mbit flash.

You can select 32Mbit on the ESP Flash Download Tool when downloading to make full use of it.
